Pseudohalogenverbindungen. Darstellung und Reaktionsverhalten von Alkyl- und Arylammoniumdicyanamiden, -tricyammethaniden und -dicyanmethanidoaceta-ten [RNH3]X (X  N(CN)2, C(CN)3, C(CN)2C(O)CH3)

Pseudohalogen Compounds. Synthesis and Reactivity of Alkyl- and Arylammonium Dicyanamides, Tricyanmethanides, and Dicyanmethanidoacetates RNH₃]X (X ? N(CN)₂, C(CN)₃, C(CN)₂C(O)CH₃) The syntheses of alkyl- and arylammonium dicyanamides, tricyanmethanido, and dicyanmethanido-acetates are reported. At higher temperatures the synthesized dicyanamides and tricyanmethanides are reacting to the corresponding cyanoguanidine and to 1,1-diamino-2,2-dicyano-ethene derivatives, respectively. The new compounds are characterized on the basis of their i.r. spectra and elemental analyses.
